ECG

Common noninvasive diagnostic test which records the electrical activity of the heart

• Echocardiogram

• Electrocardiogram

• Electrophysiology

Each small square in the ECG strips represents:

• 0.04 seconds

• 0.02 seconds

• 0.20 seconds

Each large square in the ECG strip represents:

• 0.04 seconds

• 0.20 seconds

• 0.02 seconds

P wave represents:

• Ventricular depolarization

• Atrial Depolarization

• Ventricular repolarization

• Atrial repolarizarion

PR Interval:

• represents the time from the beginning of atrial depolarization to the beginning of ventricular depolarization

• represents atrial depolarization

• represents ventricular depolarization

• Sinus Tachycardia

• Supraventricular Tachycardia

• Ventricular Tachycardia

• NSTEMI

• STEMI

• 3rd Degree AV Block

• 2nd Degree AV Block

• 1st Degree AV Block

Nursing considerations during cardioversion:

• Ensure that the skin is dry and clean

• Stop oxygen during the procedure

• Be sure that no one is touching the bed or client when delivering the shock

• All of the above

Atrial rate of >350 bpm, No definitive P wave, QRS complex usually normal

• Ventricular Fibrillation

• SVT

• Atrial Fibrillation
